4M-Motion Thermoforming

Marbach combines the »best of two worlds« through the patented 4M technology. The pointy plug supports a thin article bottom. The wide plug creates stability in the corners that are difficult to form. In the past, it was necessary to choose between these two options. Either one or the other. But not with the 4M technology. It combines the advantages of both plug shapes. The functionality is simple. The plug alters its shape during each movement. This is how optimized material distribution is achieved.
